Perforated metal, also known as perforated plate, perforated sheet or metal screen, is through punching a solid sheet metal. Sheet metal materials includemild steel, aluminium, stainless steel, pregalvanized steel, bronze, brass or other metals on request.

The most common hole types are round, square and long holes.

The cross section of the hole has a slightly conical form as a result of the punching process. The thicker the plate is, the more conical the form is.For this reason, the width of the opening is measured from the side of the penetration of the punching tool.

.Retailer sheet sizes are:

– 1000х2000 мм

– 1250х2500 мм

– 1500х3000 мм

On request,we deliver perforated sheets and coils according to your requirements.

However, there some technical limits:

– max. sheet width: 2000 mm

– max. sheet length: limited only by the length of the coil

– thickness (of sheets): from 0.5 mm to 20 mm

– thickness (coil): from 0.5 mm to 5.0 mm
